INTERNAL COMBUSTION ENGINE REMOTE ELECTROHYDRAULIC DRIVE Russian patent published in 2005 - IPC

FIELD: mechanical engineering; internal combustion engines.

SUBSTANCE: proposed remote electrohydraulic drive for internal combustion engine contains main control channels made in form of logic unit connected with main electrohydraulic distributor, standby channels at least one of which is made in form of pushbutton closers, standby power supply source, standby electrohydraulic distributor, logic OR gate and memory unit with interlock logic AND gates. Drive is furnished with setter and feedback sensor circuits break protection channel including series-connected logic AND gate and memory unit. Outputs of setter and feedback sensor are connected in parallel to inputs of AND gate of protection channel. Output of AND gate is connected to direct inputs of interlock gates AND of main control channels. Output of memory unit is connected to emergency signaling system. Memory unit reset input is connected to standby power supply source by means of command cancel discrete element. Hydraulic actuating mechanism installed directly on engine and coupled by rigid kinematic coupling with engine speed control member is connected with feedback. Said flexible kinematic feedback is made in form of cable placed inside flexible guide case secured by ends of engine in place of mounting of actuating mechanism and out of the engine, in place of mounting of feedback sensor.

EFFECT: improved reliability of remote electrohydraulic drive of internal combustion engine arranged at large distance from control station.
